Rose plant named &#39;tmro14-02&#39;

ABSTRACT

A new cultivar of  Rosa  named ‘TMRO14-02’ that is distinguishable by a semi-prostrate plant habit with pendulous branches when grown in hanging containers, mid-sized glossy green leaves, double self-cleaning fragrant flowers which open and remain lemon yellow in color until the flowers age to white. ‘TMRO-14-02’ exhibits high disease resistance and is hardy to USDA Zone 5. In combination these traits set ‘TMRO-14-02’ apart from all other existing varieties of  Rosa  known to the inventor.

CLAIM OF PRIORITY

This application is a non-provisional of and claims the benefit of priority under 35 U.S.C. 119(e) of U.S. Provisional Application No. 63/330,069 filed on Apr. 12, 2022 entitled Rose plant named ‘TMRO1402’, the entire contents of which is incorporated herein by reference for all purposes.

Genus and species: Rosa x hybrida.

Variety denomination: ‘TMRO14-02’.

BACKGROUND

The present invention comprises a new and distinct variety of rose, botanically known as Rosa x hybrida and hereinafter referred to by the variety name ‘TMRO1402’. The new variety of rose plant originated from a controlled crossing in Ipswich, United Kingdom in 2011. The crossing was between the proprietary female rose variety ‘Sweet Fairy’ (patent status unknown) and the proprietary male rose variety ‘Immensee’ (unpatented). The resulting seeds were planted and the resulting seedlings were evaluated. The new rose plant was selected in 2014 in Ipswich, United Kingdom and named ‘TMRO1402’. ‘TMRO1402’ was found to reproduce true to type in successive generations of asexual propagation carried out by the inventor in Ipswich, United Kingdom using the method of vegetative cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of the new variety ‘TMRO1402’ when grown under normal horticultural practices.

-   -   1. ‘TMRO1402’ exhibits a semi-prostrate plant habit with         pendulous branches when grown in containers.     -   2. ‘TMRO1402’ bears mid-sized glossy green leaves.     -   3. ‘TMRO1402’ bears double flowers which open and remain lemon         yellow in color for 20-25 days until first petals fall.     -   4. The flowers of ‘TMRO1402’ become white with age.     -   5. The flowers of ‘TMRO1402’ are self-cleaning.     -   6. The flowers of ‘TMRO1402’ are barren: no seed has been         observed.     -   7. The flowers of ‘TMRO1402’ are pleasantly and         characteristically rose fragrant.     -   8. ‘TMRO1402’ exhibits high disease resistance.     -   9. ‘TMRO1402’ is hardy in USDA Hardiness Zone 5.

These traits in combination distinguish ‘TMRO1402’ from all other existing varieties of Rosa known to the inventor. ‘TMRO1402’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without any variance in genotype.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘TMRO1402’.

Both drawings were made using conventional techniques and although flower and foliage color may appear different from actual color due to light reflectance, they are as accurate as possible by conventional photography.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed botanical description of the new Rosa cultivar named ‘TMRO1402’. Observations, measurements, values and comparisons were collected in Carpinteria, California from a 12 month old plant growing in a 20 cm diameter container. Color determinations were made in accordance with The 2007 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used. Growing requirements are similar to the species.
